PKCS7 Decrypt MIME

See more MIME Examples

Loads a PKCS7 encrypted MIME file and decrypts. The cert and private key used for decryption is loaded from a PFX file. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final mime = CkMime();

  // Load the MIME
  try {
    mime.loadMimeFile('encryptedMime.txt');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // The AddPfxSourceFile and/or AddPfxSourceData
  // methods may be called one or more times (one per PFX)
  // to add sources from which the MIME component will
  // search for certificates and private keys when decrypting.
  final pfxPassword = 'myPassword';
  try {
    mime.addPfxSourceFile('myCertAndPrivateKey.pfx', pfxPassword);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Decrypt...
  try {
    mime.decrypt();
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Display the decrypted MIME:
  print(mime.getMime());
}
